As far as I was aware (with over 2 decades of working in video production), there never was any predetermined definition of what data a .mov file contained. It was a simply some kind of movie file container, and over many years the .mov container has carried on existing with ever-changing types of content. Likewise with .avi files on Windows: All manner of CODECs could have been used with its contents. And there's quite a few other container formats. The filename suffix gives little clue about the content. It's been an utter disaster for us, as you get asked if you can handle a .mov file, only to have to say that we didn't know until we tried. Or the opposite, of someone saying they wanted a .mov file, and you'd ask them for more information about content, and they couldn't answer because they have no idea. Likewise with avi, mpg, mpeg, etc. You could end up going through a seriously annoying run of test files trying to find compatible formats. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
